摘　　要：文冠果属于扦插难生根树种,为明确影响文冠果扦插育苗成活的关键因素,克服文冠果扦插技术难题,以文冠果1年生硬枝为扦插试材,研究插条预处理和基质配方对文冠果硬枝扦插生根的影响。结果表明,地窖沙藏越冬插条的扦插成活率最高,为38.33%,并且生根效果最好,平均根数26.67条,平均根长5.32 cm,最长根长11.87 cm;草炭+珍珠岩(7∶3)为文冠果硬枝扦插的最适基质,其基质成活率为36.67%,平均根数21.17条,平均根长4.52 cm,最长根长11.28 cm。Xanthoceras sorbifolia belongs to the difficult rooting tree species. To clarify the key factors affecting the survival of Xanthoceras sorbifolia cuttings and overcome the technical difficulties of Xanthoceras sorbifolia cuttings, the effects of cutting pretreatment and matrix formula on the rooting of Xanthoceras sorbifolia hardwood cuttings were studied. The results showed that the survival rate of winter cuttings in cellar sand storage was the highest, which was 38.33%, and the rooting effect was the best. The average number of roots was 26.67, the average root length was 5.32 cm, and the longest root length was 11.87 cm. Peat+perlite(7∶3)was the best medium for hardwood cutting of Xanthoceras sorbifolia. The survival rate of the medium was 36.67%, the average number of roots was 21.17, the average root length was 4.52 cm, and the longest root length was 11.28 cm.
